Despite a reunion with her ex, Tiger Woods, last month, Elin Nordegren is reportedly dating billionaire coal tycoon, Chris Cline, who is 20 years her senior and the owner of Foresight Energy.

According to The New York Post’s Page Six, 33-year-old Nordegren has been “quietly dating” 53-year-old Cline, who happens to be her neighbor in Florida. The Swedish blonde former model has a home, which she demolished and re-built following her tumultuous split with Woods, nearby Cline, in the North Palm Beach oceanfront community of Seminole Landing in Florida.

“Elin and Chris have been dating since the holidays,” a source told Page Six.

However, Nordegren accompanied 37-year-old Woods last month to a youth sporting event in Jupiter, Fla., with their children, 5-year-old Sam and 4-year-old Charlie. According to TMZ, the former couple "appeared to enjoy each other's company” and were seen chatting for 30 minutes or so.

The blonde beauty and the golfer divorced in 2010 after reports surfaced that he had cheated during the couple's five-year marriage. Following the highly publicized split, it was reported that Nordegren would get anywhere between $100 million and $750 million in divorce settlements, though the exact amount was never clear.

Meanwhile reports indicate that Woods is dating Olympic skier, Lindsey Vonn, though neither camp has confirmed or denied the rumors. Page Six reported Vonn and Woods are in fact not dating.

So who is the man Nordegren is allegedly dating? Here are nine things to know about billionaire Chris Cline.
